Okay, I've got one...I guess it would be termed an 'urban fantasy', but it's about a guy who dies, and then comes back to life with Christ-like powers (Messiah might be in the title...but it's NOT Stephen King's Dead Zone, I know that). he's young, and kind of a loser, and people start making demands on him to heal them, etc. I used to think it was by Preston Child or Lincoln Douglas...but it's not. All I can remember is that in the opener, he's sitting on the fire escape and lightning strikes, nearly killing him (or killing him, not clear on that point).
And in the end, he kills himself, or something, because it's just too much.
Sorry, totally random, but.
